To meet a few points in one: In the one article i'm focused on those at the table in the highest level of discussion around the matter; those in the room on the day are what I can report on. The fact that nobody there, arguably bar Ben at PedalMe, had much to say on the need for 500W is, likely not representative of the entirety of the market. I know it's not, you only need spend 5 mins on any given forum to see that. Yet the fact remains, no hard line pro 500W advocate has stepped forward publicly and given their view, or at least nobody in the room in Parliament had yet come across/was willing to share the source. We can speculate and give opinion til the cows come home, of course, but that's outside of my remit and, dare i say, would call more criticism above and beyond that given of the facts of the day.
As an FYI - articles exist on CE that do explain things like throttles, type approval, modification/tampering etc. All covered off individually, with expert insights, but not featured in detail within each piece written.
